Jolla's first smartphone, which has no real model-name at all but often called "The Other Half" or "TOH" is available in Finland since late November and at the moment it's also shipping to everyone who preordered it from Europe. Jolla, which is a kind spin-off by former Nokia employees, is a new Finland-based mobile phone company which also developed a brand new mobile OS called Sailfish OS. This Linux-based OS is built on the heritage of the proven MeeGo OS which Nokia got rid of after it moved to Windows Phone. Therefore, everything about The Other Half is new. The hardware, the mobile operating system and the eco-system which Jolla had to create for its first smartphone.

The device itself runs - as said - on Sailfish OS and is powered by a Qualcomm Snapdragon 400 MSM 8930AA dual-core CPU at 1.4 GHz with Adreno 305 GPU. It supports GSM/GPRS/EDGE as well as UMTS/HSPA and LTE but interesting enough, Jolla hasn't given any further details about the supported bands and frequencies which is quite unusual. On top of this, The Other Half supports WiFi b/g/n at 2.4 GHz, Bluetooth 4.0+EDR HS, AGPS & GLONASS and USB2.0 HS. The Other Half comes with a unique extension interface for wireless NFC, power in/out and I2C data connectivity by allowing to change the battery cover. Last but not least, the device comes with a proximity, accelerometer, gyro, e-compass and and ambient light sensor and sports 1 GB of RAM and 16 GB of flash memory which can be expanded with a Micro SD memory card.The Ample 4.5" IPS 5-point multi-touch with Gorilla 2 Glass touchscreen has a qHD touchscreen, featuring 960x540 pixel. The autofocus main camera on the back has 8 megapixel and a supporting LED flash, the front-facing camera has 2 megapixel.All this measures 131 x 68 x 9.9 mm and weights 141 g - including the user-replaceable 2100 mAh battery, which is recharged with the included 1.0 A USB power adapter. Also included is a USB to micro USB cable but The Other Half comes without headphones.

Unlike any other smartphone, the Jolla The Other Half user interface concept is gesture-based which means there are no physical hardware buttons except the volume rocker and the power on/off button. However, the screen for example can be turned on by double taping it and turned off by sliding from the top. But that's it, there are no menu keys bellow the screen, even if there's plenty of space but this space is only used for a multi color notification LED and to slide in or out of the screen. Other gestures include to slide in from the side, to leave an app without closing it. On the bottom of the device, Jolla has located the loudspeaker for audio playback and hands-free calls. On top, right next to the USB port, is the standard 3.5 mm stereo 4-pin audio jack located.

The Jolla The Other Half is currently only and exclusively available in Finland from Finish mobile operator DNA; and it's only available with the white battery cover. The "poppy red" battery cover is an exclusive one for pre-order customers.
